We are able to announce the availability of the patch version 6.9.1 of Mantid. Installation packages can be found on our download page along with updated instructions for installing the latest release via Conda. You can also access the source code on the GitHub release page.

This patch release corrects some significant issues since version 6.9.0 was released in February.

Specifically this patch release:

• fixes a problem with workbench freezing when plotting from a workspace that is changing (e.g. plotting live data)
• Improve stability of the ReflectometryReductionOneLiveData v1 algorithm for OFFSPEC users
• Adds sample log values to the live data workspace before the instrument is loaded in ReflectometryReductionOneLiveData v1 to ensure log values are available when setting the detector positions.
• Fixes a bug in the Elwin Tab of the Data Manipulation Interface where changing integration range with the sliders did not change default integration range.
• Fixes a crash when using multiple Indirect or Inelastic Interfaces

Please take a look at the release notes, which are filled with details of all the changes and improvements. The development team has put a great effort into making all of these improvements . Thank you to everyone that has reported any issues to us and please keep on reporting any problems you have on our forum or by email on mantid-help@mantidproject.org.

Kind regards,

The Mantid Team
